How do I convert M4A to OPUS with LetsConvert?

Upload your M4A file, choose OPUS as the output format, adjust the bitrate to your preference (128kbps is recommended for transparent quality), and click Convert. Your OPUS file will be ready for download in seconds.

Why should I convert M4A to OPUS instead of keeping M4A?

OPUS provides superior compression, delivering the same perceived quality as AAC/ALAC at nearly half the bitrate. This results in smaller file sizes for streaming, podcasts, and game audio. OPUS is open-source and widely supported on modern platforms, though older Apple devices may require a player update.

Does converting M4A to OPUS lose audio quality?

Yes, because the conversion is lossy, but OPUS is optimized to discard only inaudible data. At 128kbps or above, the output is perceptually indistinguishable from the original. The converter preserves channel layout, sample rate, and metadata tags like album art and artist info.
